iOS 6 pushing viewcontrollers in a modally presented viewcontroller

Question

In my app i would like to create a tutorial to show how to use the app.

For that i presented a viewcontroller using navcontroller.presentViewController and it has a form appearance. I would like to change the viewcontroller to an other but i don't know how to.

How can this be done?

Thanks in advance!

EDIT: What i want to achieve

i'm on the mainViewController

With navcontroller.presentViewController I present the welcomeScreenViewController1 Then i want to move from welcomeScreenViewController1 to welcomeScreenViewController2 without having to dismiss welcomeScreenViewController1 first. The best would be if in that modal view, i could push welcomeScreenViewController2 onto welcomeScreenViewController1.

I hope that helps

Your modal screen needs to be a navigation controller. So you need to do :

UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:welcomeScreenViewController1];    
navController.modalTransitionStyle = UIModalTransitionStyleCoverVertical;

[self presentViewController:navController animated:YES completion:nil];

Then, you should be able to push your welcomeViewController2 in your navigation controller.
